What is Boron trifluoride acetonitrile complex?
Chemical properties
Boron trifluoride acetonitrile complex is a colorless or light yellow transparent liquid, easily soluble in water, and miscible in various organic solvents such as alcohol and ether. It is mainly used as a catalyst for organic reactions. It is an important raw material for the preparation of boron halide, elemental boron, borane, sodium borohydride and other borides.
Synthesis
Boron trifluoride acetonitrile complex can be prepared by 20% oleum, boron anhydride and fluorite(9:1:3) were stirred at 130℃ and then poured into acetonitrile to give the complexation.
